If Aetna denied your health insurance claim, you are not alone — and you have the legal right to fight back. Many Americans successfully appeal denied claims each year. This guide walks you through exactly how to appeal a Aetna denial, with insurer-specific tips, deadlines, and strategies that work.
Understanding why Aetna denied your claim is the first step to building a successful appeal. The most common denial categories are: medical necessity disputes, prior-authorization not obtained, out-of-network services, coding errors (mismatched ICD-10 / CPT codes), and treatments classified as experimental or investigational.
Under the Affordable Care Act (Section 2719), you have the right to appeal any claim denial from Aetna. You can request an internal appeal reviewed by someone not involved in the original denial, and if that fails, an Independent External Review by a physician not employed by Aetna. You can also file a complaint with your state Department of Insurance.
180 days from denial notice (internal appeal); 4 months for external review after internal appeal exhaustion. Missing this deadline forfeits your appeal rights, so act promptly.
